If you invite 100 people (aged 10 or higher) into a room that contains a red ball lying on the floor, they will each have their own perspective when asked what they see within the room. What do you think the results would be?
I actually struggle to see how responses could go beyond "a ball" or "a red ball"
It was pointed out to me via PM that I forgot a very obvious response, if you happen to be Australian or English. (Or Pakistani, Indian, South African, West Indian, Bangladeshi, New Zealander, Sri Lankan or Kenyan).
It's a cricket ball! Possibly the one used by Australia to rout the English in Perth yesterday.
